Default Just purchased 03 scr 2500

Hi, Iím new to Maxum boats. And new to the forum. I winterized my SCR today. I havenít used the head since I bought it. Boat is out of the water on trailer. Now. When I push button to flush. Nothing happens. Iím only on the primary battery. Secondary wonít hold charge. Do I need both to operate head? Holding tank could be full, where is the level indicator? What am I missing? Any help is greatly appreciated

Welcome Aboard

Since you said push the button I am assuming it's either an electric flush or vac flush. Does the fresh water tank have water or antifreeze in it? There is no factory indicator on the holding tank just a visual by looking at the tank.

If you are winterizing it the holding tank should be emptied as well as the fresh water tank and antifreeze ran through both systems.

Yes itís electric but not sure if itís vacuflush or not. The water pickup is fresh water from under boat but itís on trailer. Right now I do have antifreeze in fresh water tank but to my knowledge itís not plumbed there. Iím curious if Iím overlooking a simple circuit safety that would make the button not work. (Full tank, no water detected, blown fuse, valve closed, specific switch or breaker not on, both batteries needed, etc). Currently my second battery is not holding a charge but if Iím on shore power with battery charger on. It should compensate for that....no?

If an electric head was installed, it should have a fuse or breaker in the power lead. On aftermarket installations, this power wire is fairly hefty gauge, so most installers would run this wire directly back to the battery and use an in-line fuse close to the battery.

No safety mechanism, but a low battery issue isn't helping to isolate the issue.

If the water source is from a thru hull under the boat then it's an electric flush that uses raw water; if on the trailer there is no water to draw from and it won't function.

That’s what I was hoping. Ok but the button would not activate a pump or make noise either? Essentially just gurgle or move air? Thank you for answering so many silly questions

A Vacaflush has a foot pedal and flushes like an airplane. Electric Flush has a button. There are electric flush that use freshwater from the tank, however most use raw water.

Is the pump for the dead running and not flushing water? Or is the pump not running at all. You can pull the intake hose from the seacock, install a hose connector (male-male), then an extension of hose that goes into a bucket. Fill the bucket with marine/RV antifreeze (propylene glycol) and start flushing. Turn-on your battery charger while to do it.

NOTE:

Raw Water: Drawn from a through-hull using the water the boat is floating in. (regardless of whether the body of water is freshwater or saltwater).

Fresh Water: Drawn from the freshwater tanks.

Ok so it sounds like the pump does not run. Not sure where the fuse is but I would start there. Next verify power at the switch then the pump motor. Sometimes these pump freeze up, stuck impeller.

I put a gallon of antifreeze in and then shopvac’d it out. A water bottle cap and something else came up with that. I shut all power and try feeling around but it’s too narrow to feel anything. Next I’ll try testing power as you suggested and then report back

Is the pump running and just not flushing?

Is the pump not running at all?

Pouring in AF and vacuuming in out will not winterize the system.
